This activity shows how an ordinary ruler can measure human reaction time (RT). Learners will convert a standard ruler into a time ruler (relating time and distance) and measure each others RT. They will also calculate means and variances and the RT... (View More) required to accomplish a specific task. Additional resources and an extension to this activity are available. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This article explores how statistics can be interpreted in different ways to yield different conclusions. It describes the outcome and discussion of two class activities. In the first, the results are interpreted to "show" that taking a group rather... (View More) than an individual perspective is ultimately beneficial to the individual. In the second, a variation is added "showing" that telling the truth is better that lying.

This example explains how contour mapping teaches both estimation and spatial visualization skills. To have experience visualizing 3-dimensional fields from a 2-dimensional map helps students throughout their mathematical career. This resource is...

Logarithms are very handy when dealing with numbers at different scales but they are also useful helping us average measurements of physical phenomena that have nonlinear behavior. In this example, students learn about cloud albedo and calculating... (View More) cloud optical depth.

This poster shows comparison images of Earth and Mars on the front, with 11 Mars activities on the back. Learners can investigate: how far away is Mars, why does Mars have craters, water on Mars, Mars' minerals, how high the mountains are on Mars,... (View More) and are invited to create a martian calendar and travel guide. See Related & Supplemental Resources (right) for link to poster back where the activities are located. (View Less)

This is an activity about determining the distance of a solar flare from the center of the Sun's disk. Learners will use transparency grids overlaid on images of the Sun in order to calculate the distance of a solar flare, similar to a signal... (View More) detection method used by scientists. This is the first activity in the lesson "How Does HESSI Take a Picture?" **NOTE: The HESSI mission was renamed RRHESSI (Reuven Ramaty High Energy Solar Spectroscope Imager)** after Dr. Reuven Ramaty, who was the original Co-Investigator for this NASA mission, and was a pioneer in the fields of solar physics, gamma-ray astronomy, nuclear astrophysics, and cosmic rays.

This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept. The resource is from PUMAS -...

This is a lesson about elemental abundance in solar wind. Learners will count elements extracted from a simulated sample and learn how the extraction of atoms from the Genesis samples help scientists have a better understanding of the abundances of... (View More) elements from the solar wind. The hands-on experience helps students to discover that the elemental abundances from the sun can be used as a baseline to compare with the diverse bodies of our solar system. (View Less)
